Plate parented to "car", car is driven along a curve using follow
path constraint.
Camera has a track to constraint, tracking its view axis -Z to the Plate




Zooming in.

Here I've chosen a frame change handler. The handler takes the scene as an argument. Our camera is scene.camera, our target object is the target of the track to constraint.

The camera is put into field of view mode, and the angle is calculated by the handler. Simple equation using the diagonal length of the plate (target) and the distance from camera to target.

Copy , paste and run script below to set up the handler.

import bpy
from math import atan

def zoom_cam(scene):
    cam_obj = scene.camera
    con = cam_obj.constraints.get("Track To")
    obj = con.target
    #w = max(obj.dimensions)
    w = obj.dimensions.length # diagonal on plane.
    mw = obj.matrix_world
    cam = cam_obj.data
    l = mw.translation - cam_obj.matrix_world.translation
    cam.angle = 2 * atan(w / l.length)

# remove the previous for testing
bpy.app.handlers.frame_change_pre.clear()

bpy.app.handlers.frame_change_pre.append(zoom_cam)


Producing this result.



Mixing it up.  

Every time the handler comes to frame one could randomly set any or all of


the camera object location
the curve transform (loc, rot, scale) as well as shape keys
swap curve objects with others in scene
the plate object texture image (for different plates)  Find link re this
randomize the zooming in handler
put some noise on constraint influence
